Mobile shift
IBM’s findings is only the latest piece of data showing that consumers are increasingly using mobile to shop.

Earlier this holiday season, San Francisco-based research firm released a study that found that online retail dollars that can be attributed to mobile increased from 1.87 percent in April to 3.74 percent in December (see story).

Going forward, 2012 is expected to be a year of innovation for mobile commerce.

“We expect mobile to increase – there are more mobile devices now and retailers can be expected to build out the mobile shopping experience,” said David Selinger, CEO of RichRelevance, San Francisco.

Mr. Selinger also said that retailers can expect to see more use of interactive mobile initiatives, including check-ins, deals and games in 2012.

Additionally, eMarketer predicts that mobile commerce will total $11.6 billion in 2012, which is up from 2011’s projected $6.7 billion.

“Mobile has been growing since January, and our expectation is that we will see more overall online engagement coming in through mobile devices in the next year,” Mr. Squire said.

“There are big implications for retailers to think about the best ways to promote their products and their overall experience online for smart consumers who are using smartphones and tablets,” he said.
